It was shown that the country would benefit from the solar-hydrogen energy system economically, as well as environmentally. A similar solar-hydrogen energy system has been proposed for Pakistan as the best replacement for the present fossil fuel based energy system. This would change the vast useless desert land into green productive farms. The results of the Pakistani research indicate that adopting the solar-hydrogen energy system would eliminate the import dependency of fossil fuels, increase gross product per capita, reduce pollution, improve quality of life and establish a permanent and clean energy system. The total annual expenditure on the proposed system is less than the total income from the proposed system. The availability of water, the cash crop production, electricity and hydrogen would result in rapid development of Baluchistan, the largest province of Pakistan. Similar systems have been proposed for the high plateaus in Algeria while other researchers have proposed locating the plants at the low points of the Sahara and using gravity to bring the Sea water to the desalination systems. Several authors have proposed linking the solar hydrogen system to satellite power systems and being able to operate the plants on a 24 hour a day basis thus maximizing the return on investment. Solar Fuels One of the last pieces of the puzzle of how to create inexhaustible energy systems is the production or synthesis of liquid fuels. The idea is to create wealth. As noted above in the "Hydrogen Economy" we have become accustomed to the convenience of liquid fuels. In 1980 researchers at the U.S. Naval War College studied the concept of a nuclear powered fuel ship which would produce jet fuel from Sea water and air while steaming with a carrier battle group. Figure 13 diagrams the process. Several papers presented at the Alternative Fuels Council's Annual meeting have also described producing synthetic liquid fuels from the ultimate renewable resources: sunlight, water, and air, three of the four ancient basic elements from Greek mythology. The issue of hydrogen vs. synthetic fossil fuels has been studied and reported on in the International Journal of Hydrogen Energy. From the summaries a much more comprehensive table can be compiled. The data is reported in gigajoules (GJ) where one gigajoule is approximately equal to 947,900 Btu's or 1.055 GJ equals one million Btu's. Table 3 - Cost of electrolytic hydrogen in 1984 S
